Current display devices for vehicles lack the ability to effectively transmit diverse driving information in a manner that intuitively conveys the depth and importance of safety-critical notifications, particularly in dynamic driving situations.

Innovation Solution

A display device comprising a first and second display, along with a tiltable light synthesizing unit that adjusts the reference angle based on driving conditions, allowing for the generation of three-dimensional visual information and varying the output position and size of displayed objects to enhance notification effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple displays are used to provide diverse driving information, then the quantity of information is improved, but the device complexity increases

Engineering Contradiction:
Improvequantity of driving informationVSAvoiddisplay device complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent combines multiple display devices (first display and second display) into a single integrated display system. The light synthesizing unit merges the light paths from both displays, allowing diverse driving information to be presented through a unified optical path while maintaining the functional benefits of multiple information sources.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The light synthesizing unit serves multiple functions: it transmits light from the first display, reflects light from the second display, and directs both light paths toward the same viewing direction. This multi-functional component enables the system to provide diverse information without proportionally increasing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a fixed display configuration is used, then the device complexity is reduced, but the adaptability to different driving situations deteriorates

Engineering Contradiction:
Improveadaptability to driving situationsVSAvoiddisplay device complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The light synthesizing unit is designed to be tiltable with an adjustable reference angle, transforming the display system from a static configuration to a dynamic one. This allows the system to adapt to different driving situations by changing the angle at which information is presented, while the adjustment mechanism remains relatively simple.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If visual information is displayed without depth differentiation, then the ease of operation is improved, but the loss of information deteriorates

Engineering Contradiction:
Improveease of information perceptionVSAvoiddepth information loss
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent introduces a depth dimension to the visual information display by using a tiltable light synthesizing unit. Information from the second display is reflected at an angle to create a sense of depth and layering, allowing critical safety information to be visually distinguished from general information without complicating the user interface.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case
